| pK' | apparent value of a pK; negative logarithm of the dissociation constant of an acid |

| dissociation constant of water | Expressed by the equation [H+][OH-] = Kw = 10-14 at 25캜. (05 Mar 2000) |
|---|---|
| dissociation sensibility | The loss of the pain and the thermal senses with preservation of tactile sensibility or vice versa. (05 Mar 2000) |
| incomplete atrioventricular dissociation | A-V dissociation interrupted by ventricular captures. (05 Mar 2000) |
| interference dissociation | The simultaneous operation of two separate cardiac pacemaking foci that are unassociated because of interference (a normal physiologic phenomenon) due to rendering their respective territories refractory to each other. Usually atrioventricular dissociation is indicated, the rates being quite close to each other with the atrial rate slightly faster than that of the pacemaker in control of the ventricles. Capture is in either direction, usually the ventricle by the atrium, in incomplete dissociation. H Synonym: dissociation by interference. (05 Mar 2000) |
| isorhythmic dissociation | <cardiology, physiology> A-V dissociation characterised by equal or closely similar atrial and ventricular rates. (05 Mar 2000) |
| tabetic dissociation | Loss of proprioceptive sensation with retained pain and temperature sensation due to involvement of the posterior columns of the spinal cord. (05 Mar 2000) |
| theory of electrolytic dissociation | The theory of electrolytic dissociation (1887) that became the basis of our modern understanding of electrolytes: in an electrically conductive solution (e.g., acid, base, or salt), free ions are present before electrolysis, and the proportion of molecules dissociated into ions can be calculated from measurements of electrical conductivity as well as of osmotic pressure. Synonym: Arrhenius law. (05 Mar 2000) |
| electromechanical dissociation | Persistence of electrical activity in the heart without associated mechanical contraction; often a sign of cardiac rupture. (05 Mar 2000) |
| light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| longitudinal dissociation | Dissociation between parallel chambers of the heart, as between one atrium and the other or between one ventricle and the other, in contrast to dissociation between atria and ventricles. (05 Mar 2000) |
